A study using genetically modified mice shows that a protein called Nrf2 increases the expression of protective genes in the acrylamide-induced toxic response.

A research group used live tissue imaging for the first time to visualize the emergence of the mammary gland.

Depression in youth, between the ages of 10 and 24 years, is both a leading cause of stress and a possible risk factor for future diseases and impairment. Now, a study confirms that depression in childhood or adolescence is associated with higher level…

This model addresses the fact that most traditional climate models effectively ignore cities entirely, causing them to underestimate the frequency and severity of urban heat waves. Urban areas make up only 2-3% of the earth’s land, so their effect on g…

A study of ancient bones on South Australia’s Kangaroo Island has provided new information about the Island’s past fauna and an insight into how species may live there in the future.

A research team discovers that silver (Ag)-based antimicrobials can effectively combat antibiotic resistant Staphylococcus aureus by targeting multiple biological pathways via functional disruption of key proteins and can be further exploited to enhanc…

To tackle the challenge of global warming, scientists have been looking into green and sustainable methods of breaking down carbon dioxide in emissions and in the atmosphere. Now, a group of researchers have developed a novel, easy to synthesize compos…

Scientists have used a compound made from a starch derivative and baking soda to help convert mechanical to electrical energy. The approach is cost-effective and biocompatible, and can help charge low-energy electronics like calculators and watches.

Researchers found a direct link between global dispersion of nickel-rich aerosols, ocean chemistry changes and the end-Permian mass extinction event that took place 251 million years ago.

When a research team reported last year that North American migratory birds have been getting smaller over the past four decades and that their wings have gotten a bit longer, the scientists wondered if they were seeing the fingerprint of earlier sprin…

High blood pressure is a risk factor for cognitive decline and dementia in older adults. Studies have shown that commonly prescribed high blood pressure medications, or antihypertensives, may have a positive, beneficial impact on cognitive function inc…

By 2050, more than 70% of the world’s population will live in cities. Researchers have developed software that shows city planners where to invest in nature to improve people’s lives and save billions of dollars.

Researchers have found that certain commensal bacteria that reside in the human intestine produce compounds that inhibit SARS-CoV-2.

Researchers have optimized a new technique that will allow scientists to evaluate how potential inhibitors work on antibiotic-resistant bacteria. This technique, called native state mass spectrometry, provides a quick way for scientists to identify the…

Although two SARS-CoV-2 variants are associated with higher transmission, patients with these variants show no evidence of higher viral loads in their upper respiratory tracts compared to the control group, a new study found.

The combination of sea level rise, tides, storm surge and waves has increased the overtopping of natural and artificial coastal protection by nearly 50% in the last two decades.

For the most accurate accounting of a product’s environmental impact, scientists look at the product’s entire life cycle, from cradle to grave. It’s a grand calculation known as a life cycle assessment (LCA), and greenhouse gas emissions are a key comp…

An incredibly light new material can reduce aircraft engine noise and improve passenger comfort. The graphene oxide-polyvinyl alcohol aerogel weighs just 2.1kg per cubic meter, making it the lightest sound insulation ever manufactured.

A new study finds that convalescent plasma from recovered COVID-19 patients can dramatically improve likelihood of survival among blood cancer patients hospitalized with the virus. The therapy involves transfusing plasma from people who have recovered …

By cleverly combining complementary sequencing techniques, researchers have deepened our understanding of the function of known RNA molecules and discovered thousands of new RNAs. A better understanding of our transcriptome is essential to better under…
